Gerfried Fuchs uploaded new packages for drupal6 which fixed the
following security problems:
CVE-2010-2250
A user-supplied value is directly output during installation allowing
a malicious user to craft a URL and perform a cross-site scripting
attack. The exploit can only be conducted on sites not yet installed.
CVE-2010-2471
The API function drupal_goto() is susceptible to a phishing attack. An
attacker could formulate a redirect in a way that gets the Drupal site
to send the user to an arbitrarily provided URL. No user submitted
data will be sent to that URL.
CVE-2010-2472
Locale module and dependent contributed modules do not sanitize the
display of language codes, native and English language names properly.
While these usually come from a preselected list, arbitrary
administrator input is allowed. This vulnerability is mitigated by the
fact that the attacker must have a role with the 'administer
languages' permission.
CVE-2010-2473
Under certain circumstances, a user with an open session that is
blocked can maintain his/her session on the Drupal site, despite being
blocked.
CVE-2010-3091
The OpenID module in Drupal 6.x before 6.18, and the OpenID module 5.x
before 5.x-1.4 for Drupal, violates the OpenID 2.0 protocol by not
verifying the openid.return_to value, which allows remote attackers to
bypass authentication by leveraging an assertion from an OpenID
provider.
CVE-2010-3092
The upload module in Drupal 5.x before 5.23 and 6.x before 6.18 does
not properly support case-insensitive filename handling in a database
configuration, which allows remote authenticated users to bypass the
intended restrictions on downloading a file by uploading a different
file with a similar name.
CVE-2010-3093
The comment module in Drupal 5.x before 5.23 and 6.x before 6.18
allows remote authenticated users with certain privileges to bypass
intended access restrictions and reinstate removed comments via a
crafted URL, related to an "unpublishing bypass" issue.
CVE-2010-3094
Multiple cross-site scripting (XSS) vulnerabilities in Drupal 6.x
before 6.18 allow remote authenticated users with certain privileges
to inject arbitrary web script or HTML via (1) an action description,
(2) an action message, (3) a node, or (4) a taxonomy term, related to
the actions feature and the trigger module.
CVE-2010-3685
The OpenID module in Drupal 6.x before 6.18, and the OpenID module 5.x
before 5.x-1.4 for Drupal, violates the OpenID 2.0 protocol by not
checking for reuse of openid.response_nonce values, which allows
remote attackers to bypass authentication by leveraging an assertion
from an OpenID provider.
CVE-2010-3686
The OpenID module in Drupal 6.x before 6.18, and the OpenID module 5.x
before 5.x-1.4 for Drupal, violates the OpenID 2.0 protocol by not
ensuring that fields are signed, which allows remote attackers to
bypass authentication by leveraging an assertion from an OpenID
provider.
For the lenny-backports distribution the problems have been fixed in
version 6.18-1~bpo50+1.
For the unstable (sid) and testing (squeeze) distributions, the problems
have been fixed in version 6.18-1.
Upgrade instructions
--------------------
If you don't use pinning (see [1]) you have to update the package
manually via "apt-get -t lenny-backports install <packagelist>" with
the packagelist of your installed packages affected by this update.
[1] <https://backports.debian.org/Instructions>
We recommend to pin the backports repository to 200 so that new
versions of installed backports will be installed automatically.
